**FastAPI**가 `BackgroundTasks` 타입의 객체를 생성하고 해당 매개변수로 전달합니다.

## 작업 함수 생성 { #create-a-task-function }

백그라운드 작업으로 실행할 함수를 생성합니다.

이는 매개변수를 받을 수 있는 표준 함수일 뿐입니다.

`async def` 함수일 수도, 일반 `def` 함수일 수도 있으며, **FastAPI**가 이를 올바르게 처리하는 방법을 알고 있습니다.

이 경우 작업 함수는 파일에 쓰기를 수행합니다(이메일 전송을 시뮬레이션).

當然，這並不理想，你不會在生產環境這樣做。

在生產環境你通常會用上述其中一種方式。

但這是能讓我們專注於 WebSocket 伺服端並跑起一個可運作範例的最簡單方式：

{* ../../docs_src/websockets_/tutorial001_py310.py hl[2,6:38,41:43] *}

## 建立一個 `websocket` { #create-a-websocket }

在你的 **FastAPI** 應用中，建立一個 `websocket`：

{* ../../docs_src/websockets_/tutorial001_py310.py hl[1,46:47] *}

/// note | 技術細節

你也可以使用 `from starlette.websockets import WebSocket`。

Первое, что нужно сделать, — импортировать `BaseModel` из пакета `pydantic`:

{* ../../docs_src/body/tutorial001_py310.py hl[2] *}

## Создайте модель данных { #create-your-data-model }

Затем опишите свою модель данных как класс, наследующийся от `BaseModel`.

Используйте стандартные типы Python для всех атрибутов:
